Going to need loom elastics. For beginners I would just use 1-3 colors for the pattern.
Take off the middle one
Cross the first one
Then just put the second one on (not crossed)
And the third.
Take the crossed one and over lap the "blue" elastic over top on the 2 other colors
Push them down and then add the color that you just overlapped
Add the color u just overlapped
Pull on the "soon to be bracelet" every couple times you do it
When you have it to the length you want over lap it one more time
And over lap the second one
The pull the last one over to the other one
Then stretch it across to put the clip on
Then stretch the other side and connect the clip
There you have it
